James Hargreaves

James Hargreaves (1720-22 April 1778) was a British weaver, carpenter, and inventor from Oswaldtwistle, Lancashire, England. In 1764, he invented the spinning jenny spinning frame after his daughter Jenny knocked over his wife's spinning wheel; Hargreaves designed a horizontal wheel that could spin more threads on more spools. He was one of the most important inventors of the Industrial Revolution.
